## What is F2S?

Block social media until you can prove you've learned something.

F2S intercepts your social media habit and turns it into a study session. When you open Instagram, TikTok, or any app you choose, F2S steps in with a quiz. Answer correctly by explaining concepts in your own words, and earn your scroll time. Fail, and try again.

It's the Feynman Technique meets screen time control.

HOW IT WORKS
• Upload your study notes, PDFs, or any learning material
• AI generates quiz questions from YOUR content
• When you try to open a blocked app, F2S intervenes
• Answer 3 voice-based questions by explaining concepts out loud
• Pass the quiz → earn 15 minutes of scroll time
• Track your streak, daily stats, and average score

WHY VOICE?
Typing an answer is easy to fake. Speaking forces you to actually understand. The Feynman Technique says: if you can't explain it simply, you don't understand it. F2S puts that to the test every time you reach for social media.

SMART LEARNING
• AI validates your spoken explanations in real time
• Spaced repetition brings back questions you struggled with
• Questions adapt to your study materials, not generic trivia
• Focus mode lets you drill specific topics before an exam

BUILT FOR YOUR WORKFLOW
• Works with iOS Shortcuts for seamless app blocking
• Sign in with Apple — no new account needed
• Cloud-synced across all your devices
• Clean, minimal design that stays out of your way
